Two former Horseshoe Casino employees are accused of running a $25,000 cheating scam, the Ohio Casino Control Commission announced on Friday.

Andrew Grzelewski, a table games supervisor at the casino and Thomas Coffey, a former dealer, were indicted on felony gaming charges for allegedly altering mini baccarat card decks.

Grzelewski would place a predetermined sequence of cards into the deck, said OCCC officials. He would then signal Coffey to place "significant wagers" on the game.

Gaming agents were made aware of the scam in 2014. In all, the cheating resulted in a loss of more than $25,000.

Coffey also implicated his mother, Susan, and Lando Camp as accomplices. They are indicted on felony counts of cheating at a casino game.

“Casino cheaters do more than simply break the law – they are also stealing from the state and the citizens of Ohio,” said Matt Schuler, OCCC Executive Director.

A Grand Jury also returned an indictment against a former Horseshoe craps dealer.

Gemini Isham was indicted on three gaming charges following an investigation that showed he facilitated cheating by a known felon by adding chips to his bets, according to OCCC.

The investigation found more than 150 alleged instances of cheating between Isham and Keith Washington, resulting in a loss of more than $96,000. Washington was also indicted on three gaming charges.

On Friday, the Horseshoe Casino released a statement about the alleged incident. Below is the full statemnt:

"We do not comment on pending litigation, however we take these matters very seriously. Our security and surveillance teams work closely with the Ohio Casino Control Commission and local authorities to monitor gaming activity around the clock.
